Presumably we need to restyle on document URI changes.  Probably only when regexp() rules are used, because otherwise pushState/popState will get prohibitively slow.

Alternatively, maybe @-moz-document shouldn't include the hash portion of the URI?

That may not help with pushState(), right?

I think we schould keep this feature. It's a useful alternatve to the :targe pseudo-class and it's the only way to style more than just one element in a dynamic site.

Or we propose a new one, like target() or id()

Comment 6

[Cameron McCormack (:heycam)]

The current plan is just to support a url-prefix() hack in bug 1446470, so I don't think we need to do anything for regexp().
